IMPROVEMENT IN MACHINES FoR SCORING scREw-CAPS.

Specification forming part ofLetters Patent No. 147,163, dated February3, 1874; application filed December 3, 1873.

To all whom' it may concern:

Be it known that I, FRANK W. PERRY, of the city and county of Camden andState of N ew Jersey, have invented a new and useful Apparatus forScoring Sheet-Metal Screw-Gaps; and I do hereby declarethe following tobe a clear and exact description of the nature thereof, sufiicient toenable others skilled in the art to which my invention appertains tofully understand, make, and use the same, reference being had to theaccompanying drawings Inaking part of this specification, in which-Figure l is a central vertical transverse section of the deviceembodying my invention. Fig. 2 is a front view of a detached portion.Fig. 3 is a horizontal section in line xx, Fig. 2. Fig. 4 ris a frontview. Fig. 5 is a front view of a detached portion enlarged. Fig. 6 is atop view of a scored screw-cap. Fig. 7 is a central section thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

It is well known that sheet-metal screw-caps are applied to cans andother packages to contain oil and other uids, and that it is importantthat the top or central portion of the two sections or parts of the capsare solid or closed to prevent leakage between the joints thereof. Itis,however, essential that when the can or package reaches its destination,one of the sections or caps has its center or top cut away to form anopening for the discharge of the fluid.

My invention is designed for the purpose of scoring, half-cutting, orthinning a portion of one section of the cap, whereby said portion is incondition to be readily cut by a knife or other suitable implement. Theinvention consists in a rotary knife-cutter or bit. It also consists ofa feedingspindle. It further consists of a spindle for holding the capwhile being cnt. It also consists in means for imparting a dwell tothefeeding-spindle. It also consists in a screw for regulating the depthof the cut or score.

Referring to the drawings,'A represents the main shaft, having bearingsin a suitable frame or support, B. O represents a shaft which receivesmotion from the shaft A, and imparts motion to a horizontal shaft, D,suitable intermediate gearing being provided therefor, and

the shaft l) carries, at the end opposite to its l geared end, a cam,F.. A pulley, F, is attached to the shaft C, and, by means of a band, G,and

arranged spindle, J, which is mounted on the frame B and has an openingits entire length, and through the opening passes a spindle, K, whoseupper end is angular and passes through an angular opening in an arm, L,which holds and guides the upper end of said spindle K, while the mainportion of the latter is within the spindle J, whereby' said spindle Kis permitted to rise and fall within the spindle J, but without havingrotary motion therewith. M represents a spindle, which is mounted onsuitable arms of the frame B and arranged vertically under the spindlesJ K. The lower end of this spindle M carries a screw, N, which rests onthe cam E, and its upper end is formed with or has connected to it ahead, P. A spring, Q, is arranged with the spindle M and proper portionsof the frame B, for forcing the said spindle downwardly and against thecam E. The lower en d of the inclosed spindle K carries a head, It, andbearing against its upper end is a spring, S, whose tendency is to keepthe spindle K to its lowest point.I T represents a knife, cutter, orbit, which is connected to the lower end of the spindle J, and in thepresent case said knife is tted in a groove, a, in the spindle, acollar, b, passed around the shank ofthe knife, and a screw, c,introduced through the collar to bear against the shank of the knife.The cam E is so constructed that'when, in rotation, it raises thespindle M to its highest point, it reaches the point d. Then, the facedf, being the are of a circle whose center is the shaft D, bears againstthe spindle M without elevating the same, thus causing what is termed adwell of said spindle, after which the spindle clears the point fof thecain E and drops to its normal position. c

The operation is as follows: A screw or other spindle M, and, as thelatter is elevated by the cam E, the cap is advanced toward the knife T,land comes in contact with the inclosed spindle K, which, while beingraised by the raising of the spindle M, bears against the metal cap, andwhen the spindle M is at its highest point pulley H, imparts rotarymotion to a verticallysheet-metal cap is placed on the head of thethe'said cap is iirmly held by the spindle K,

due to the action of the spring S. When said highest point of thespindle M is reached, then the dwell oeours, and the knife Tis inContact with the upper face of the metal eap, and, in its path ofrotation, caused to eut a channel in the said upper face of the cap,near the periphery thereof, this constituting the score of the eap (seeg, Figs. 6 and 7,) and vcompleting the scoring operation. The spindle Mthen drops, the cap is removed therefrom, and a fresh eap applied. Thedegree of penetration of the knife is readily adjusted by the screw N inthe spindle M.

Having thus described 1ny invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The knife T, having` a rotary motion and operating for scoring themetal cap presented to it, substantially as set forth.

. 2. The feeding-spindle M, having a risingand-falling motion andoperating for presenting the lnetal cap to the scoring-knife,substantially as set forth.

3. The holding-spindle K, in connection withA the feeding-spindle M andscoring-knife T, substantially as and for the purpose set forth.

4. The risingand-falling spindle K inolosed within the rotary spindle J,in combination with the feeding-spindle M arranged thereunder, andraising the said spindle K, in the manner and for the purpose set forth.

5. The combination, with the feeding-spindle M and scoring-knife T, ofthe cam E, oonstrueted to impart a dwell to the said feedingspindle, asset forth.

6. The adjusting-screw N, in combination with feeding-spindle M of anapparatus for scoring metal caps, substantially as set forth.
